No clue, but they do go well with the overall look of his face and body. It's kinda funny, imo, how his face actually looks like the Decepticon logo. The toy, for only being a Deluxe, is very accurate to the show, including a majority of his pop out accessories, and what appears to be a spring loaded missle in his main gun. I do hope his torso gun can retract and be able to go into his torso somehow.
